I'm not sure the notion of employee or job is going to survive the transition over the next couple of decades. The very notion of a fulltime job will seem as quaint in 20 years as the notion of someone getting a gold watch at their retirement in the 1950s.

Each time you toss out a 'singing' greeting card, you are disposing of more computing power than existed in the entire world before 1950.

Think about reading: Today, parents would love it if their kids read books more because the parents understand the books. Just over 100 years ago, parents were upset because their kids were reading dime-store novels. Parents would say, "I don't want you inside reading anymore. Get outside and play." I guarantee you, in 50 years or so, parents are going to say, "You're not going outside to play until you finish that video game."

If you look at the last 150 years, about every 30 years or so, a new scientific discipline emerges that starts spinning out technologies and capturing people's imaginations. Go back to 1900: That industry was chemistry. People had chemistry sets. In the 1930s, it was the rise of physics and physicists. They build on each other. Chemists laid the experimental understanding for the physicists to build their theories. It was three physicists who invented the transistor in 1947. That started the information revolution. Today, kids get computers.

I think it is just a matter of time before we have literal ghosts in the machine so you can create an alter ego of yourself that learns from your social experiences and extends a life even if you're no longer in the game or you are no longer alive.

Digital technology is the solvent leaching the glue out of all of our traditional institutions.

Sometimes I think we're on this world for three reasons: to be useful, to tell each other stories and to collect stuff. It's the only explanation for eBay. We love to collect stuff, and at least if we're collecting stuff in cyberspace we're not deforesting the Sierra Nevada.
